%X <strong>Objective:</strong> The purpose of this study was to investigate cephalometric norms for two Sub-Saharan populations residing in Morocco the Hausa and Somali, and to compare these norms with those of Steiner and Tweed. <strong>Method:</strong> A total of 40 lateral cephalometric radiographs from Hausa and Somali students in Casablanca area, aged 18 to 32 years, with Class I dental occlusion and facial harmony, were analyzed. Twenty cephalometric variables, comprising 14 angular and 6 linear measurements, were calculated and compared with reference norms, as well as those of other Arab, Asian, and European populations, using the Z-test for statistical evaluation. <strong>Results:</strong> The Hausa population exhibited an advanced sagittal position of both the maxillary and mandibular skeletal bases, an increased vertical dimension, and a more pronounced vestibular version of the incisors compared to the reference norms. In contrast, the Somali population demonstrated a more retruded sagittal position of the maxillary and mandibular bases, an increased vertical dimension, and a greater buccal version of the incisors. Conclusion: These findings emphasize the distinct cephalometric features of the Hausa and Somali populations, which should be considered in orthodontic treatment planning to ensure more accurate and population-specific care.<br />
